In Peter Jackson’s Lord of the Rings prequel trilogy, The Hobbit, there was a dragon under the mountain. That dragon was named Smaug and Smaug’s voice belonged to Benedict Cumberbatch.

While watching the scaley computer animated beast terrorize Laketown, it may have been easy not to think about what anybody looked like while lending their voice to Smaug. However, now that the trilogy has long since wrapped up and we can look back on it, a video of Benedict Cumberbatch in character, as Smaug, has surfaced.

Not only does Cumberbatch voice the fire-breathing monster but, in fact, also gets in character to bring him to life. See it for yourself in the video below.

Cumberbatch’s dedication and ability to become Smaug the Dragon should have everyone excited for Doctor Strange, where he’ll play the titular Stephen Strange in the Marvel Cinematic Universe on November 4, 2016.

It’s the end of a long day of interviews for Benedict Cumberbatch and he seems almost giddy as he gazes wishfully out of a hotel-room window in Toronto. Suddenly, he says excitedly: “I was in the elevator with Bill Murray yesterday. It was f—ing fantastic! I stepped into the elevator in a bathrobe and he went, ‘oh this guy is up for the same underwear ad that I am’. And then he stepped over to me and whispered, ‘You won’t get it, I’ve already got it’.

“He was so funny, I was completely starstruck.”

These days it’s usually the other way around when the 38-year-old actor walks into a room. In the past three years, Cumberbatch has graduated from being known mostly for stage work in his native England to a name brand whose films have included best-picture Oscar winner 12 Years a Slave, the Meryl Streep dramedy August: Osage County and the Julian Assange story The Fifth Estate.

This year, the actorhas all his eggs in one basket at the Toronto Film Festival, but what a basket. He’s an Oscar favourite and Golden Globe nominee for his complex role in The Imitation Game as English mathematician Alan Turing, who virtually invented the first computer and during World War II broke the enigma codethat helped end the war years earlier, only to be persecuted by his own country later for being homosexual.

It’s not the first time Cumberbatch has played a character much smarter than him, he admits. His title character in the television series Sherlock enjoys being a pompous arse and as Khan in Star Trek: Into the Darkness he’s no dummy either. But nothing prepared the actor for the journey of Turing, who was finally issued an official pardon and apology from the Queen this year, 60 years after he committed suicide following his chemical castration for homosexuality.

Sophie Hunter and Benedict Cumberbatch.

“I got to know my character very well and by the time we shot the scene where he breaks down in front of Joan [Keira Knightley] at the end, I had no control over my emotions,” he says. “I couldn’t stop crying and it wasn’t good acting, it was just because I knew that I was mourning this extraordinary human being who I had become so fond of. I can’t remember another time that it’s happened to me in my career, but it’s a desperately moving story and it deeply affected me.”

Asked about his own maths skills, Cumberbatch looks speechless. “My what? Oh, I thought you said my romance skills, as we sit here alone in an empty bedroom’,” he deadpans, then chuckles. “Yes, I’ll admit they are pretty awful and even now I vaguely panic when somebody give me arithmetic to do, because it’s just not my strong suit.”

The fiercely private Cumberbatch likes to waffle on in interviews about the intricacies of his character’s motivations until he runs the clock down without saying anything too personal, I’ve discovered in the past. Today he’s tired, so maybe his defences are down a little because he’s surprisingly funny, even joking about how he navigates a world of being constantly watched and recorded.

“What’s interesting is that you walk a minefield because everyone is a walking publisher, so anything you do in public isn’t private, and it’s all up for scrutiny,” he says. “The funniest ones are the people who pretend they are on the phone so they can take a photograph and think you don’t notice. I go right up to them and shock them by asking if I can see the picture!”
Catching up with Cumberbatch again last month, he was in Los Angeles doing his bit for his film’s award chances but pining for some quiet time at home in London. “I like being in nature – that’s why l live near the Heath, because I just love the fact there’s ancient woodland on my doorstep in the middle of London,” he says.

He’d just announced his surprise engagement to his girlfriend Sophie Hunter via a paid-for announcement in the classifieds section of The Times, naming both their parents.

“It’s the standard way of doing it in England and it may seem old-fashioned now but I would have done that if I wasn’t in this strange, heightened position that I am as a famous actor, so it’s just to try and normalise something that’s deeply personal to me I guess,” Cumberbatch says.

Was he old-fashioned in his proposal? “That’s something for me to know and you to never find out,” he says with a polite grin.

Much has been written about the actor and two friends being kidnapped in 2005 by armed robbers in South Africa, only to be released unexpectedly from the trunk of a car. He has been quoted many times as having promised himself at that time that if he survived he would live a life less ordinary. “Have I done that?” he jumps in, knowing where the question is going. “I would say I have done pretty well since then – as he says in his empty hotel room!”

Being seen and heard

Benedict Cumberbatch can be seen in just one film this holiday season, but his voice can be heard in two others: as Smaug the dragon in The Hobbit: The Battle of the Five Armies (out now) and as Classified, the head of a pack of wolf spies aiding the black-and-white heroes in the animated Penguins of Madagascar (January 1).

“Penguins and dragons are very different animals, excuse the pun,” Cumberbatch says of his voice work. “Because Smaug came out in motion-capture form, the movement completely informed the voice … But the Penguins part was extraordinary in a different way because we recorded over a long period of time and had a lot of fun and freedom.

“All disciplines of acting feed off one each other and they all require different energies,” he adds. “So I am not exhausting myself doing just one thing.”

The stars of The Hobbit were in London for the world premiere of the new film

Stars of The Hobbit: The Battle of the Five Armies gathered together for a giant group photo at the world premiere of the new film at London’s Leicester Square on Monday night.

Benedict Cumberbatch – who plays Smaug in the hit film – was among those posing for photos.

The 38-year-old actor was working a blue velvet suit jacket, black trousers and shiny shoes as he walked the green carpet to the sound of screaming fans.

Cumberbatch – who presented the Lebedev Award to Sir Tom Stoppard at the London Evening Standard Theatre Awards on Sunday evening – was joined at the event by his fiancée Sophie Hunter who looked stunning in a green lace floor length dress.

Also adding a touch of glamour to the event was actress Evangeline Lilly – who plays elf Tauriel in The Battle of Five Armies. With her chic bob sleeked back she glided down the green carpet in a white Reem Acra gown with embellished corset top before briefly covering up from the cold in a black jacket as she posed for selfies with fans and signed autographs.

Orlando Bloom was looking suave in a Lanvin suit as he posed for photos with Sir Ian McKellen. The 75-year-old actor jazzed up his long grey suit jacket with a patterned scarf, while co-star Martin Freeman – who plays Bilbo Baggins in the franchise – was sporting a polka dot tie and pocket hanky.

Director Sir Peter Jackson was in attendance and addressed the crowd, saying: “We hope you enjoy this film. We make it for you, for the fans and the people who enjoy these movies so I hope you like this one.”

The premiere was streamed live to more than 160 countries, and some fans – who donned Hobbit inspired clothing – had camped on the streets for five days to get a glimpse of the cast.
